A. W. MOGOWN SAFETY RAZOR Aug. 6, 1940.

Filed Dec. 5, 1936 A .mw wlw ATTORNEYS Patented Aug. 6, 1940 n UNITED stares animer Arent orties 1 Claim.

This invention relates to safety razors and has for an object to provide a safety razor having a springpressed spindle provided with jaws for detachably mounting the cap, the spindle being movable longitudinally of the tubular handle of the safety razor to project the blade andv the cap away from the guard so that the blade may be easily cleansed by simply reciprocating the spindle up and down with the blade immersed in water, without touching the blade with the hands.

With the above and other objects in View the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure l is a, side elevation of a safety razor constructed in accordance with the invention.

Figure 2 is a longitudinal sectional view through the parts sho-wn in Figure 1 with the spindle and cap shown dotted in projected position.

Figure 3 is an enlarged cross sectional view taken on the line 3 3 of Figure 2,

Referring now to the drawing in which like characters of reference designate similar parts in the various views, I0 designates the cap which is provided with positioning pins II which pass through openings I2 in the guard I3 in the usual manner. 'I'he cap is provided with a stud I4 having a substantially rectangular head I5 best shown in Figure 3, the stud being centered between the positioning pins I I,

AThe guard I3 is formed integral with a tubular handle I6 which slidably receives a spindle I'I which is substantially twice the length of the handle. The spindle is provided in one side with a longitudinal guide groove vI8 which is disposed near the outer en-d of the spindle and receives a guide pin I9 which is threaded through an opening in the tubular handle and through a bushing 2D inserted in the end of the tubular handle which bushing provides a bearing for the spindle. Sliding movement of the spindle, when the handle is grasped between the fingers and the thumb placed upon the outer end of the spindle, is limited by contact of the pin I9 with the ends of the groove I8.

A helical spring 2l is sleeved upon the spindle within the tubular handle and is confined under tension between a stop` collar 22 on the spindle and a shoulder 23 formed in the bore of the handie nearthe guard. The spring returns the spindle to neutral position after each forward movement thereof due to pressure of the operators thumb.

n The spindle terminates in a pair of jaws 24 which are out away at their inner ends to provide a recess 25 to receive the head I5 of the stud I4. The shoulders 26 formed in the jaws at the outer end of the recess 25 hook over the head E5 of the stud land detachably secure the cap to the spindle. When the spindle is moved outwardly the cap may be rotated through part of a turn to dispose the head I5 so as to disengage from underneath the shoulders 26 and pass outwardly between the jaws to permit removal of a used blade. Since the cap is concave translversely as shown in Figure l the jaws will strike the cap if an attempt is made to remove the head of the razor by sliding it transversely between the jaws thus rendering necessary a partial rotation of the head as a preliminary step to removal from the stem.

In operation, after use of the razor in shaving in order to thoroughly cleanse the razor, it is simply necessary to invert the razor from the position shown in Figure 2 and submerge the cap, blade and guard in a container of water and then reciprocate the blade andcap up and down` by coaction of the thumb and fingers of thek hand and the spring 2I. During such reciprocation the cap and blade will move freely up and down through a stroke equal to the length of the guide groove I8 and thus the blade will be thoroughly cleansed in minimum time without need of the operators ngers touching the blade.

It will be further pointed out that by releasing the spring 2| and then turning the cap I0 slightly and allowing the unperforated portion of the guard to come to rest on the positioning pins II, the razor and blade can be cleaned at any time during the operation of shaving, by inverting the same in water and moving the razor up and down. The blade moves up and down freely or independently between the cap Ill and the guard I3 and in this way is thoroughly cleansed and need not be wiped or dried as after cleaning and removal from the water the air has free access to all parts. Should the blade accidentally rotate about the upper end of the spindle I'I when cleansed, it is an easy matter to engage the blade with the guide pins II preliminary to assembling the razor for use.

From the above description it is thought that will be fully understood without further explanation.

What is claimed is:

A safety razor comprising a cap, spaced positioning pins` on the cap, a guard having openings removably receiving the pins, a stud on the cap centered between the pins and terminating in a substantially rectangular head, a tubular handle integral with the guard, a spindle slidably mounted in the handle, said spindle being substantially twice the length of the handle and projecting from the outer end of the handle, there being a longitudinal groove in the spindle exposed beyond the handle, a bushing in the end of the handle forming a bearing for the spindle, a guide pin threaded through the handle and bushing and projecting into said groove to limit sliding movement of the spindle, a collar on the spindle adjacent to the bushing, a shoulder formed in the bore of the handle near the guard, a helical spring sleeved on the spindle near the handle and confined under compression between the collar and the shoulder, and a pair of jaws formed on the inner end of the spindle detachably receiving the head of the stud, pressure of the operators thumb against the projecting end of the spindle While the handle is held stationary serving to move thecap to disengage the positioning pins from the guard and permit the cap being spaced from the guard to facilitate cleaning of the razor blade.
